76 Duster 318, a few issues...

The only way to get to the wiper linkage is from under inside. Your going to have to remove the heater box. And if the fuse box is melted there is a short somewhere. Try to find a donor wiring because you don't want anything to catch fire. And sorry to remove the whole dash you have to take the front class out there are 5 screws that hold it on top and one on each side on the inside. Good luck man!
